In an embodiment, when a detected sensing value is smaller than a preset threshold, the display device 100 may wait for to determine whether an additional sensing value is detected without identifying a touch area. When the detected sensing value is smaller than the preset threshold, the display device 100 may determine that touching by the mobile device 200 is not intentional.

In an embodiment, the display device 100 may receive from the mobile device 200 a second sensing value sensed by the sensing unit 291 included in the mobile device 200. The display device 100 may determine whether the second sensing value is greater than or equal to a preset threshold.

In an embodiment, when it is determined that the second sensing value is greater than or equal to the preset threshold, the display device 100 may determine that the display device 100 is touched by the mobile device 200. When it is determined that the second sensing value is smaller than the preset threshold, the display device 100 may determine that touching of the display device 100 by the mobile device 200 is not intentional.

In an embodiment, the display device 100 may determine whether the display device 100 is touched by the mobile device 200 by comparing a result of at least one sensing value detected by the sensing unit 191 with a result of the second sensing value received from the mobile device 200. The display device 100 may determine that the display device 100 is touched by the mobile device 200 when it is determined that the at least one sensing value detected by the sensing unit 191 and the second sensing value received from the mobile device 200 are similar within a preset range.

In this case, the display device 100 may transmit a pairing request signal (e.g., a BLE pairing signal). In addition, the display device 100 may receive a response signal from the mobile device 200.
